I am having asus S400CA triple booting windows 8.1, mavericks and ubuntu 13.10.
Before installing ubuntu, I have intial efi partition boots windows and another colver efi partition used to boot osx. After installing ubuntu, I get menu options to boot ubuntu, windows and osx. First two works ok. osx does not boot from the option. How to make ubuntu menu to run osx or any other alternative to boot either one from single menu.
